Structure of Matter [electronic resource] : An Introductory Course with Problems and Solutions / by Attilio Rigamonti, Pietro Carretta.

Atoms: general aspects -- Typical atoms -- The shell vectorial model -- Atoms in electric and magnetic fields -- Nuclear moments and hyperfine interactions -- Spin statistics, magnetic resonance, spin motion and echoes -- Molecules: general aspects -- Electronic states in diatomic molecules -- Electronic states in selected polyatomic molecules -- Nuclear motions in molecules and related properties -- Crystal structures -- Electron states in crystals -- Miscellaneous aspects related to the electronic structure -- Vibrational motions of the ions and thermal effects.

Intended Audience, Approach and Presentation This text is intended for a course of about four months for undergraduate students. Itarisesfromtheadaptationandtheamendmentstoatextforafu- yearcourseinStructureofMatter,writtenbyoneoftheauthors(A. R. )about thirty years ago. At that time only a few (if any) textbooks having the suited formforintroductiontothebasicquantumpropertiesofatoms,moleculesand crystalsinacomprehensiveandinterrelatedway,wereavailable.

Still there are reasons,inouropinion,toattemptafurthertextdevotedtothequantumroots of condensed matter properties. A practical aspect in this regard involves the organization of the studies in Physics, after the huge scienti?c outburst of the varioustopicsoffundamentalandtechnologicalcharacterinrecentdecades. In most Universities there is now a ?rst period of three or four years, common to all the students and devoted to elementary aspects, followed by an advanced program in more specialized ?elds of Physics. The di?cult task is to provide a common and formative introduction in the ?rst period suitable as a basis for buildingupmoreadvancedcoursesandtobridgetheareabetweenelementary physics and topics pertaining to the research activities. The present attempt towards a readable book, hopefully presenting those desired characteristics, essentially is based on a mixture of simpli?ed institutional theory with solved problems. The hope, in this way, is to provide physical insights, basic culture and motivation, without deteriorating the possibility of advanced subsequent learning.

Thepresentstatusofthat VI Preface discipline represents a key construction of the scienti?c knowledge, possibly equated only by the unitary description of the electromagnetic phenomena.
