    Mean 24-hour growth hormone and testosterone concentrations in relation to pubertal growth spurt in boys with normal or delayed puberty (1976)
    Springer
    European journal of pediatrics 122 (1976), S. 85-92

    Notes: Abstract The mean growth hormone concentration during a 24-hour period in 7 boys of short familial stature and a growth rate of 3.2–5.4 cm/year was between 1.0 and 4.6 ng/ml serum. In 7 boys with pubertal growth spurt and familial tallness (growth rate 7.2–11.0 cm/year) it varied from 0.97 to 4.4 ng/ml and in 6 boys with constitutional delay of puberty (a growth rate of 4.2–5.2 cm/year prior to puberty) from 1.3 to 4.3 ng/ml. No correlation was found between the 24-hour mean growth hormone concentration and the mean 24-hour testosterone concentration in serum or the growth rate, but a correlation was found between testosterone and the growth rate. It is concluded that the growth spurt in puberty is not due to a change in growth hormone concentration but rather to the increase of androgen production in puberty.

    Nuclear magnetic resonance on oriented 11/2− 129mXe and131mXe in Fe (1987)

    Notes: Abstract The magnetic hyperfine splitting frequenciesν M=¦gμ NBHF/h.¦ of the 11/2− isomeric states129m Xe (T1/2=8.9d) and131mXe (T1/2=11.8d) in Fe were measured with nuclear magnetic resonance on oriented nuclei at temperatures of 10–15 mK as 188.0(1) MHz and 209.8(1) MHz, respectively, the samples being prepared with the technique of recoil implantation after (α, x n) reactions. The magnetic moments of129m Xe and131m Xe are deduced to be (−)0.8914(6)μ N and (−)0.9943(6)μ N, respectively. The missing γ-anisotropies for allγ-transitions following the decay of 36.4d 127Xe indicateI=1/2 for the ground state spin of127Xe.
