    Notes: Abstract Fourteen21Ne(p, γ)22Na resonances have been observed in the rangeE p =300–1,300 keV. Theγ-decay of all these resonances has been investigated by means of a 38 cm3 Ge(Li) detector. Energies and branching ratios of several bound states have been determined. TheQ-value was determined as 6,738.5±1.7 keV. Lifetimes of seven states were determined with the Doppler-shift attenuation method. The observed upper limit (τ m ≦4 fs) of the lifetime for the 4,071 keV state, regarded as the analogue of the third excited state in22Ne, and the transition observed from this state to the 1,528 keV state do not support the proposed rotational band structure of the22Na low-lying states.

    Notes: Abstract The level scheme of144Pr has been studied from the decay of144Ce. The intensities and energies of gamma rays have been determined with a X-ray Ge(Li) detector. TheK-shell internal conversion coefficients for γ-rays have been measured with theK X-ray/γ-ray ratio method using NaI(Tl)—X-ray Ge(Li) coincidence techniques.

    Investigation of gamma ray transitions and lifetimes in35Cl (1973)

    Notes: Abstract Fortyeight resonances of the34S(p, γ)35Cl reaction in the proton rangeE p=1–2 MeV have been observed. Gamma decay of twentyeight of these was investigated by means of a 55 cm3 Ge(Li) detector, and the energies and branching ratios of several bound states have been determined. TheQ-value was found to be 6367.0 ± 1.5 keV. The lifetimes 150±20, 400±140, 19±4, 14±2, 145±50, 20±5, 20±4, 42±4 and 7±3 fs were determined with the DSA method for the states at 1219, 1763, 2694, 3003, 3944, 3967, 4059, 4178 and 4882 keV, respectively. The experimental transition strengths were found to be in agreement with those given by manyparticle shell-modell calculations.

    Notes: Abstract The gamma decays of 1922Ne(p, γ)23Na resonances in the range ofE p =400−1300 keV have been investigated by means of a 38 cm3 Ge(Li) detector. Branching ratios of the resonances and bound states were determined. Gamma-ray energy measurements yield the energies of 19 bound states and the value of 8794.0±1.5 keV forQ. The existence of the 3913 keV doublet state was studied through the (p, γ) reaction. No evidence for such a doublet was found.

    A method for the determination of recoil ion ranges needed in DSA measurements (1972)

    Notes: Abstract From the yield curve of the27Al(p, γ)28Si reaction obtained with implanted targets, the range distributions and mean ranges of 50 keV Al+-ions have been determined in C, Cu, Mo and Ta. The energy straggling of protons has been taken into account in the analysis. The DSA lifetime values in different backing materials are in good agreement when measured ranges are used for the determination of the stopping parameters.

    Angular distribution measurements of gamma-rays from the22Ne(p, γ)23Na reaction (1972)

    Notes: Abstract Angular distribution measurements of gamma-rays from the22Ne(p, γ)23Na reaction on theE p =897, 1006, 1091 and 1278 keV resonances have been made. Spin and parity assignments for several bound states are presented together with multipole mixing ratios for transitions from resonance and bound states. The level at 6617 keV (7/2+) is proposed to be a member of the rotational band based on the Nilsson orbit 5(K π=5/2+).

    Notes: Abstract Resonances in the reaction58Fe(p, γ)59Co have been studied in the analogue regionE p =2.20–2.25 MeV. Theγ-ray decays of fourteen resonances and the energies of nine bound states have been obtained using a 80 cm3 Ge(Li)-detector. TheQ-value was found to be 7359.7±3.0 keV. One lifetime and six lifetime limits were determined from the Doppler-shift attenuation method for bound states.
