“…The data on neutron strength functions are due either to the analysis of average capture cross sections or of neutron resonance parameters. P-wave neutron strength functions obtained so far (Gibbon et a2 1961, Chaubey and Sehgal 1965, 1966, Bilpuch et a2 1960, Murty et al 1973, Siddappa et al 1974 from the analysis of average capture cross sections are dependent on certain assumptions made about the P-wave gamma-ray strength function and the P-wave neutron reduced width distribution in the absence of experimental data on P-wave resonance parameters. Sand P-wave gamma-ray strength functions had been assumed to be equal (Gibbon et a1 1961, Chaubey and Sehgal 1965, 1966 a1 …”

P-wave neutron strength functions for 20 nuclei have been extracted from the average radiative capture cross sections u(n, y) at 24 keV, using the latest available values of (T,o), (DO), SO, (r,l) and (01) in contrast to the earlier analysis where certain assumptions were made about the P-wave resonance parameters. Our values for the P-wave strength functions are compared on the one hand with previous experimental 'local' values and on the other hand with the theoretical predictions of the optical model of Buck and Perey.I NUCLEAR REACTIONS Sand P-wave resonance parameters, u(n,y), E , = 24 keV, Bilpuch expression; deduced P-wave neutron strength functions.

“…Furthermore, Murty et al [5] completed the data set for the mass range 60<A<140 by 21 new $1 values for 23 keV neutrons. They deduced the same high value as reported by Krueger and Margolis.…”

Using a silicon filtered fission neutron beam of an energy width of 20 keV around 143 keV we measured the total cross sections for 37 nuclides and elements having mass numbers between 87 and 140 and determined the p-wave strength functions. The 3P-resonance at A = 98 shows no splitting into the P3/2-P1/2 doublet.The narrow resonance peak and the following broad distribution of the p-strength function (A = 103 to 140) can approximately be reproduced by deformed optical model calculations. The spin-orbit term in the optical potential is consistent with the spin orbit force in the shell model. For nuclei around the closed (N= 50) neutron shell a shell effect in the p-wave strength function is indicated.
