Abstract

An element is non-composite but composes other particles. None of the over 200 elementary particles of Modern Standard Model however satisfies this definition. The elementary quarks & leptons of MSM are found to be compressible and assembleable, hence have composition and are non-element. These in Unified Theory are composed by new elements: positrino & negatrino, named cosminos of diameter 1.6156x10^-33 cm, mass 2.596x10^-48 gm, electric charge ? 1.3729x10^-30 esu and spin ? ?. Mutual repulsion among cosminos of same electric charge, however, makes quarks fragile and non-existent as intact units. So color charge is not a basic cosmino charge. Weak too is not a basic cosmino charge as it does not conserve. The two cosminos constitute the new particle ?sharmon' which composes the light propagating ?sharmon medium' as the all-composing and all-pervading ?basic substance'. The cosmino-sharmon composition-structures of electron, proton and neutron presented for the first time are defined by concentric regions in Fig-1 and Form Factors describing spatial distribution of charge, mass, sharmons, diads and diad-sharmon units etc. It is shown that no ?-spin Fermion like neutron can be neutral. The Electric Dipole Moment of neutron 5.83x10^-45 esu.cm = 1.2x10^-35 e.cm calculated from Unified Theory agrees with observations. An almost neutral neutron emits electron, never positron, because its outer region is negative. Hofstadter's positive outer region in neutron is inconsistent with negatron decay. Effect of superimposed magnetic field on neutron's negatron decay is explained without Electroweak Theory's weak charge and W^? & Z^o particles. A new Hook's law mediated short-range nuclear force is suggested, which obviates the need for inter-quark strong nuclear force mediated via ?-mesons.
