Production cross sections of products in the proton induced reactions on natNd in the energy region up to 45 MeV

Activation cross sections of proton induced nuclear reactions on neodymium up to 65 MeV

“…The agreement between all experimental datasets of Yang [19] and also with the theory is good both in shape and in magnitude.…”

“…Three reactions participate in the production of 146 Pm (T1/2 = 5.53 y) by proton irradiation of nat Nd as shown in the excitation function with three distinct maxima. There is an energy shift between the earlier experimental data set of Lebeda [16,17], but the agreement is considered acceptable by comparing to other activation measurements of Yang [19] (Fig. 5).…”

“…The cooling times for the different series of measurements are indicated in Table 1. As a detailed discussion on production routes and contributing reactions can be found in the earlier report of Lebeda et al [16,17] and Yang et al [18,20,19], we discuss them only briefly here to avoid repetitions.…”

“…Our thick target yields were calculated from fited curves to our experimental cross-section data and some literature data with acceptable agreement with ours in order to fill the hole between our two series. In the case of Yang data [19] thin target yields were published, which should be converted into thick target yields. The results represent so called physical yields (obtained in an instantaneous irradiation time) [32,33].…”

“…Searching the literature for activation cross sections of proton induced nuclear reactions on neodymium, three works have been found up to 38 MeV, i.e. by Lebeda et al [16,17], and the recent data of the Korean group up to 45 MeV protons [18][19][20].…”
