Beta (UK: , US: ; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα, romanized: bē̂ta or Greek: βήτα, romanized: víta) is the second letter of the Greek alphabet. In the system of Greek numerals it has a value of 2. In Ancient Greek, beta represented the voiced bilabial plosive /b/. In Modern Greek, it represents the voiced labiodental fricative /v/ (while /b/ in foreign words is instead commonly transcribed as μπ). Letters that arose from beta include the Roman letter ⟨B⟩ and the Cyrillic letters ⟨Б⟩ and ⟨В⟩.
How would you target and isolate a new particle when using beta particles against a alpha target (negative vs positive)? I know you would have to use a particle accelerator of somesort. I am interested in different particles that can be targeted using a particle accelerator.
