The importance of Hamada's equation is that it separates the risk of the business, reflected here by the beta of an unlevered firm, β U, from that of its levered counterpart, β L, which contains the financial risk of leverage. Apart from the effect of the tax rate, which is generally taken as constant, the discrepancy between the two betas ...
The two types of beta decay are known as beta minus and beta plus.In beta minus (β −) decay, a neutron is converted to a proton, and the process creates an electron and an electron antineutrino; while in beta plus (β +) decay, a proton is converted to a neutron and the process creates a positron and an electron neutrino. β + decay is also known as positron emission.
The line of stable nuclides down the center of the valley of stability is known as the line of beta stability. The sides of the valley correspond to increasing instability to beta decay (β − or β +). The decay of a nuclide becomes more energetically favorable the further it is from the line of beta stability.
In nuclear physics, a beta decay transition is the change in state of an atomic nucleus undergoing beta decay. When undergoing beta decay, a nucleus emits a beta particle and a corresponding neutrino , transforming the original nuclide into one with the same mass number but differing atomic number (nuclear charge).

Shares of Unilever (NYSE: UL) were marching higher today after the consumer packaged goods giant posted strong results in its second-quarter earnings report. As a result, the stock was up 5.4% as ...
In theory, quadruple beta decay may be experimentally observable in three of these nuclei – 96 Zr, 136 Xe, and 150 Nd – with the most promising candidate being 150 Nd. Triple beta-minus decay is also possible for 48 Ca, 96 Zr, and 150 Nd; [37] triple beta-plus decay or electron capture is also possible for 148 Gd and 154 Dy.
Investors who are nervous about stock-market swings and loathe to put assets in safer bonds are turning to smart-beta strategies. After the fourth quarter stock market sell-off, low-volatility ...
