K:th forbidden unique beta transitions are a subgroup of the beta decays and phase space integrals depict the final states after a decay and for example give important knowledge about a decay constant of a transition. The phase space integrals for many known beta decays having a two or more times forbidden unique transition was calculated numerically in this thesis. The calculation data was then analyzed through\r\nvarious ways. The most important point of view is a ratio of the phase space integrals\r\nbetween a forbidden transition and an allowed transition of the same decay.\r\nThat ratio gives most information about how the degree of K affects the phase space integral. According to the results in the transitions with small decay energy the allowed\r\nones were dominating. But when the energy grows the phase space integrals of the forbidden transitions become larger and the increase is the faster the bigger the K is. The next point of view is the ratio between the phase space integral of the forbidden beta decay and the decay energy which gives information about the average number of the final states in transition. These results were similar to the previous point of view. When the decay energy increases the ratio increases too and the bigger is K the faster is the increasing. The third point of view was to compare the ratio between the phase space integrals of beta+ decays and electron captures. Because these two types of beta decays can occur simultaneously theirs phase space integrals always sum up. It is already known that decay energy and the atomic number of the nuclear influence the ratio between these two types. According to this thesis, however, also the degree of the forbiddenness seems to have an influence. Higher degree of K seems to prefer electron captures. Finally phase space integrals without taking into account the screening effect of the electron cloud was compared to those with taking into account. The results didn\u2019t have a significant difference nor the degree of K would seem to have any influence to that.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Antti Kasslin (ansekass) on 2018-01-10 10:54:11.060992.
