Abstract

Production of ¹⁰¹Ag with a (p, 2n) reaction on ¹⁰²Pd targets has been observed. A half-life of 10.8±0.2 min was measured for the new isotope, and the subsequent growth and decay of its daughter ¹⁰¹Pd was detected. A complex position spectrum was resolved into energies and intensities of 3.38 MeV (10.0%), 2.73 MeV (43.6%), 2.18 MeV (22.6%), 1.56 MeV (17%), 1.08 MeV (6.2%) and 0.85 MeV (0.6%). Nine gamma transitions from 83 keV to 1164 keV have been identified as belonging to the decay of ¹⁰¹Ag. The most intense gamma transition at 263 keV is fed by the high-energy position branch and establishes the energy available for decay at 4.665±±0.08 MeV. A level scheme is proposed with a positive parity assignment for the first excited energy level in ¹⁰¹Pd.

The 1961 version of the Nuclear Data Sheets for A = 101 has been revised on the basis of experimental data published prior to September 1 1972. The present evaluation contains information obtained from approximately 70 papers.
There are currently nine nuclei known for A = 101. Only the presumed ground states and half-lives have been determined in ¹⁰¹Zr and ¹⁰¹Cd. Decay-scheme studies of ¹⁰¹Zr and ¹⁰¹Cd have established two levels in ¹⁰¹Nb and ¹⁰¹Ng, respectively.
The identification of levels in ¹⁰¹Mo and some subsequent spin and parity assignments depend primarily on recent sub-Coulomb stripping results. The identification of levels in ¹⁰¹Mo fed by the β-decay of ¹⁰¹Nb is somewhat uncertian at this time. Nine levels in ¹⁰¹Pd have been identified from the β-decay study of ¹⁰¹Ag, but the data are not sufficient to assign spins and parities. ε/β⁺-decay studies of ¹⁰¹Pd have established approximately 19 levels in ¹⁰¹Rh and have resulted in some tentative spin and parity assignments.
During The course of the compilation, the results of 72Col6 and 72Co17 concerning the β-decay of ¹⁰¹Mo were communicated to the compilers. This study resulted in the identification of 152 transitions and the placement of approximately 45 levels in ¹⁰¹Tc. In addition, conversion-electron work resulted in the identification of previously unobserved levels in ¹⁰¹Tc at 0.009317 and 0.15601 MeV, requiring a reassignment of level energies in ¹⁰¹Tc. The stable nucleus ¹⁰¹Ru has been studied via β-decay, γ-decay, and Coulomb excitation. As a result, a number of spin assignments for low-lying states are firm.
Some additional gaps and uncertainties remain in the data. The relative intensities of transitions depopulating the same levels in ¹⁰¹Ru as observed in β-decay, Coulomb-excitation, and γ-decay studies do not agree in some cases. Reaction studies would help to confirm the spins of low-lying states in ¹⁰¹Tc and ¹⁰¹Rh and provide additional information on higher spin states in ¹⁰¹Mo. The existing data on levels in ¹⁰¹Pd populated by the β-decay of ¹⁰¹Ag were obtained in early work with semi-conductor detectors and are probably incomplete at this time.
